Analysis of Characteristics and Abnormal Noise of Check Valve Based on a Simulation Model
This article takes the check valve for braking system of rail vehicles for object and studies the causes of the abnormal noise in its service.Firstly,the simulation software Amesim is used to build up the simulation model for the check valve and the effectiveness of the simulation model is verified by comparing the static and dynamic characteristic indicators in simulation and in full scale test.On this basis,the causes of the abnormal noise are analysed according to the structural principle of the check valve.It studies the impact of different environmental parameters on the dynamic characteristics of the check valve,discusses the impact of different structural parameters on the dynamic characteristics of the check valve core by means of parameterization to conclude the main structural factors influencing the dynamic characteristics,proposes the optimization method to eliminate the abnormal noise of the check valve and verifies the effectiveness of the optimization method with the full scale test.
